TROPICAL STORM (TS) 22W (NALGAE), LOCATED APPROXIMATELY 885 NM
EAST-NORTHEAST OF MANILA, PHILIPPINES HAS TRACKED WESTWARD AT 05
KNOTS OVER THE PAST SIX HOURS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
281200Z IS 15 FEET. NEXT WARNINGS AT 282100Z, 290300Z, 290900Z AND
291500Z. REFER TO TYPHOON 20W (NESAT) WARNINGS (WTPN31 PGTW) FOR SIX-

SUBJ/PROGNOSTIC REASONING FOR TROPICAL STORM 22W WARNING NR 06//
RMKS/
1. FOR METEOROLOGISTS.
2. 12 HOUR SUMMARY AND ANALYSIS.
A. TROPICAL STORM (TS) 22W (NALGAE), LOCATED APPROXIMATELY 885 NM
EAST-NORTHEAST OF MANILA, PHILIPPINES HAS TRACKED WESTWARD AT 05
KNOTS OVER THE PAST SIX HOURS. ANIMATED INFRARED (IR) SATELLITE
IMAGERY SHOWS TIGHTLY CURVED CONVECTIVE BANDING WRAPPING INTO A LOW
LEVEL CIRCULATION CENTER (LLCC). A 281030Z SSMIS MICROWAVE IMAGE
DEPICTS A SMALL DEEP CONVECTIVE MICROWAVE EYE. THE INITIAL POSITION
IS BASED ON THE IR AND SSMIS IMAGERY WITH GOOD CONFIDENCE. THE
INITIAL INTENSITY IS BASED ON THE PGTW, KNES, AND RJTD DVORAK
ESTIMATES RANGING FROM 45 TO 55 KNOTS. WATER VAPOR IMAGERY INDICATES
AN AREA OF DRY AIR WRAPPING AROUND THE NORTHWESTERN PERIPHERY.
HOWEVER, EQUATORWARD OUTFLOW REMAINS GOOD AND POLEWARD OUTFLOW INTO
A MID-LATITUDE TROUGH HAS IMPROVED. TS 22W IS CURRENTLY TRACKING
ALONG THE SOUTHERN PERIPHERY OF A MID-LEVEL SUBTROPICAL STEERING
RIDGE.
3. FORECAST REASONING.
A. NO CHANGE TO FORECAST PHILOSOPHY.
B. THE SYSTEM IS EXPECTED TO TRACK GENERALLY WESTWARD THROUGHOUT
THE FORECAST PERIOD. AS A SUBTROPICAL RIDGE BUILDS IN FROM THE
NORTHWEST, TS 22W SHOULD STEADILY BEGIN TO INCREASE IN TRANSLATION
SPEED. TS 22W IS FORECAST TO INTENSIFY DUE TO FAVORABLE OUTFLOW AND
WARM SEA SURFACE TEMPERATURES. NUMERICAL MODEL GUIDANCE IS IN GOOD
AGREEMENT ESPECIALLY IN THE INITIAL 36
HOURS. AFTER TAU 36, THE TRACK SPEEDS DIFFER AS EGRR AND ECMWF ARE
FORECASTING FASTER TRACK SPEEDS WITH A STRONGER STEERING RIDGE TO
THE NORTH. THIS FORECAST IS IN AGREEMENT WITH MODEL CONSENSUS.
C. AFTER TAU 72, TS NALGAE WILL WEAKEN AS IT CROSSES THE NORTHERN
TIP OF LUZON AND CONTINUE TRACKING WESTWARD INTO THE SOUTH CHINA
SEA.//
